The conceptual model was displayed at the American Institute of Aeronautics and Astronautics SciTech forum in Orlando.

The "airplane concept and associated technology are targeted for a hypersonic ISR (reconnaissance)/strike aircraft that would have the same type of mission as the SR-71," Boeing spokeswoman Sandra Angers told Business Insider in an emailed statement. "In that sense it could be a future replacement for the SR-71."

"It's a conceptual model for an eventual demonstrator, but no one has committed to building a reusable hypersonic demonstrator yet," Angers added. "We're constantly looking to advance concept in technology areas that could someday be asked for by the customer."

Boeing is one of the largest defense contractors and political donors in the US.

Angers also told Business Insider over the phone that the future generation concept would be able to hit speeds of more than Mach 5.

Aviation Week also reported that Boeing "envisions a two-step process beginning with flight tests of an F-16-sized, single-engine proof-of-concept precursor vehicle leading to a twin-engine, full-scale operational vehicle with about the same dimensions as the 107-ft.-long SR-71."

Boeing has already experimented with two unmanned hypersonic planes, the X-43 and X-51, according to Popular Mechanics.

In 2013, Boeing tested the small X-51, which hit speeds of Mach 5.1 for more than three minutes before crashing into the ocean, Popular Mechanics reported. The X-51, however, was dropped from a B-52 and used a jettisoned booster to reach Mach 5.1.

Boeing's conceptual design will have to take off and land on its own, which is much harder, Popular Mechanics reported.

GREENBELT, Md. (Reuters) - A U.S. Coast Guard lieutenant accused of amassing a cache of weapons and plotting to attack Democratic politicians and journalists was ordered held for two weeks on Thursday while federal prosecutors consider charging him with more crimes.

Attorneys for the Constitutional Law Center for Muslims in America have filed a lawsuit against Secretary of State Mike Pompeo, Attorney General William Barr and President Donald Trump asking the court to recognize the citizenship of an Alabama woman who left the U.S. to join ISIS and allow she and her young son to return to the United States.

WASHINGTON (Reuters) - The United States will leave "a small peacekeeping group" of 200 American troops in Syria for a period of time after a U.S. pullout, the White House said on Thursday, as President Donald Trump pulled back from a complete withdrawal.

With a legal fight challenge mounting from state governments over the Trump administration's use of a national emergency to construct at the U.S.-Mexico border, the president has kicked his push for the barrier into high gear.

On Wednesday, President Trump tweeted a time-lapse video of wall construction in New Mexico; the next day, he proclaimed that "THE WALL IS UNDER CONSTRUCTION RIGHT NOW"

But there's a big problem: The footage, which was filmed more than five months ago on Sep. 18, 2018, isn't really new wall construction at all, and certainly not part of the ongoing construction of "the wall" that Trump has been haggling with Congress over.

A group comprised of former U.S. military veterans and security contractors who were detained in Haiti on weapons charges has been brought back to the United States and arrested upon landing, The Miami-Herald reported.

The men — five Americans, two Serbs, and one Haitian — were stopped at a Port-au-Prince police checkpoint on Sunday while riding in two vehicles without license plates, according to police. When questioned, the heavily-armed men allegedly told police they were on a "government mission" before being taken into custody.
